Question No.1. Differences between Static analysis and Dynamic analysis are as below: Static Analysis 1. Load do not varies with time and effect of time on the application of load is neglected as the load is applied slowly such slow that it is not comparable with natural vibration freequency of the structure. 2. Motion…

Answer for 1.a) Mode of Failure: Concrete crushed and the reinforcement is exposed. Its form of Flexure Failure. Flexural failure has occured due to reversal of Stresses during the earthquake. At support, due to stress reversal top of the beam experiences compression and bottom of the beam experiences Tension. Top compression…
